moving to a bigger tank

[wonkybumcrack]

I'm getting a 200l tank Tomorrow currently have a 130l. How's best to move the fish into the new tank? Should I do a new cycle and move them after 2 weeks or put the water from the old tank and gradually top up the water?

Moving water sources nothing. The bacteria live in your filter, not in the water. Set up the new tank and get the water to the right temperature. Move your filter and fish over to the new tank. Job done.

Sources was meant to say Achieves

Thank you new tank comes with a external filter so can I run both filters?

Yes, it's really important to transfer your mature filter across so you don't lose the cycle. Only swill the filter in old tank water. Never run it under the tap as the chlorine will kill the bacteria.

Always dechlorinate fresh tank water.

I have tap safe and always clean filter in old tank water. I have got myself the bigger tank as a treat I was given the other tank and got a few fish and have done good with them. Thank you

Sounds great. You should post a picture when you've set the new one up.

I will. Filled it up last night just waiting for temp to rise.

Here it is!

That's a beaut. Nice one!
